Effects of feedforward control on cancellation rate in femtosecond laser assisted cataract surgery

Objective To explore the effects of feedforward control on cancellation rate in femtosecond laser assisted cataract surgery. Methods From March 2018 to March 2019, we selected patients with femtosecond laser assisted cataract surgery in Cataract Operating Room at Beijing Tongren Hospital of Capital Medical University as subjects by convenience sampling. A total of 267 patients with femtosecond laser assisted cataract surgery from March 2018 to September 2018 were in control group; a total of 319 patients with femtosecond laser assisted cataract surgery from October 2018 to March 2019 were in observation group. Patients of control group carried out routine nursing for cataract day surgery. On the basis of that in control group, observation group implemented feedforward control management. We compared the day's surgery cancellation rate and patient satisfaction of between two groups. Results On the same day, the surgery cancellation rates of patients of observation group and control group were 4.1% (13/319) and 14.2% (38/267) with a statistical difference (χ2=17.615, P<0.01) . The patient satisfaction of observation group and control group was 97.3% (288/296) and 92.1% (222/241) with a statistical difference (χ2=7.468, P<0.01) . Conclusions Application of feedforward control in femtosecond laser assisted cataract day surgery of Ophthalmology Department can effectively reduce the day's surgery cancellation rate and hospital waste of resources, and improve patient satisfaction.
